Unit testing in the WordPress backend (is_admin() is true)

According to this test, you use set_current_screen() to navigate to one of these in the setUp method. Alas, none of this is apparent if you look at the tremendously-helpful reference page for get_current_screen()… Example: <?php class AxisSetupTest extends WP_UnitTestCase { /** * @covers AxisWP::__construct */ function test_constructor() { // Assert // Admin $this->assertInternalType(‘integer’, has_action( ‘admin_enqueue_scripts’, … Read more
